CANNING APPARATUS.

Application filed March 18, 1921.

T 0 all whom it may concern:

Be it known that I, EMIL W. R. KUenL, a citizen of the United States, residing at Benedict, in the county of York and State of Nebraska, have invented certain new and useful Improvements in Canning Apparatus, of which the following is a specification.

This invention relates to apparatus for canning and preserving in accordance with what is known as the cold pack process.

The object of the invention is to provide a simple, cheap and efficient cooker of this character which is composed of a mimimum number of parts united so that there is no danger of them being displaced thereby insuring proper positioning of the food con tainers at all times without necessitating any adjusting of the cells.

WVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and specifically pointed out in the claims.

In the accompanying drawings:

Figure 1 represents a longitudinal vertical section through a cooker constructed in accordance with this invention.

Fig. 2 is a transverse section thereof with a container shown in dotted lines therein.

Fig. 3 is a detail plan view of the cooker and,

Fig. 4 is a detail perspective view of two of the intersecting cell-forming strips or partitions.

The cooker constituting this invention preferably comprises a metallic vessel 1 preferably constructed of sheet metal such as galvanized iron and which is here shown rectangular in configuration although obviously it may be of any other desired shape. This vessel 1 is provided at its upper end with an inturned flange forming a reinforcing bead 2 at the open end thereof and is equipped with a removable closure 3 having a downturned flange 4t fitting snugly around the outer face of the vessel 1 in substantially watertight relation. This top or closure 3 is provided with a plurality of steam outlet apertures or perforations 5 as shown in Fig. 1, both the vessel and the top being equipped with suitable handles to facilitate lifting thereof and the removal of the top.

Within the vessel 1 is provided a cellular structure comprising a series of intersecting sheet metal partitions 6 and 7 which may be f y u a le e des red Wid h nd a Specification of Letters Patent.

Serial No. 453,506.

equipped, respectively, with transversely e:-: tending slots 6 and '7 one opening through the lower edge of one strip and the other through the upper edge of the other strip so that when the strips are assembled they will interlockingly engage to hold them in planes at right angles to each other, the strips 6 and 7 in Fig. a being shown arranged in juxtaposition ready for assembling, the slot 6 in strip 6 opening through the lower edge thereof, while the slot 7* in strip 7 opening through the upper edge. The

free ends of the strips 6 and 7 are equipped with right angularly extending attaching flanges 8 which bear against the opposed side cured thereto by soldering, riveting or otherwise, the structure comprising these strips being preferably arranged about midway the height of the vessel although obviously it may be disposed at any desired height therein. The cells 9 formed by this struc ture are designed to receive the food containers indicated in F ig. 2 by dotted lines which are usually in the form of glass jars having screw tops such as are commonly known in the canning and preserving art.

Extending from one end to the other of the vessel 1 on the bottom thereof are a plurality of metal strips 10, six being here shown and each provided with a plurality of upstruck container supports 11, each strip having four as is shown clearly in Fig. 2 to provide one for each of the cells 9, there being twenty-four cells in the receptacle or vessel 1 herein shown. six in each series extending longitudinally of the vessel and four transversely thereof. These strips 10 extend transversely of the vessel 1, as is shown clearly in Figs. 2 and 3 with an upstruck support 11 positioned centrally at the bottom of each cell 9 to receive and support the container and hold it out of contact with the bottom proper'of the vessel 1 to avoid all danger of breaking of the receptacle when the contents become heated and to permit the free circulation of the water used in the vessel 1 around the containers. The portions 12 between the supports 11 extend under the longitudinal partition strip 7 and are secured to the bottom of the vessel 1 by soldering or otherwise.

In the use of this apparatus the food to be canned or preserved is first packed in the containers land said containers are placed in the vessel 1, one in each cell 9 and. supwalls of the vessel and are se 1 ported on the upstruck strip portion 11. The vessel 1 is then filled with cold water and placed over a steady lire, it of course being understood that the top 2 is placed on the vessel before or immediately after the placing thereof over the fire. The water in the vessel 1 is brought slowly to a boil and allowed to continue to boil for a predetermined time suflicient to thoroughly sterilize the contents of the containers C. fter they have been sterilized the tops are placed thereon and screwed down tight thereby excluding all air and effectively sealing the containers C so that the material therein will be preserved indefinitely. 7

From the above description it will be obvious that the strips 10 and the cellular structure being permanently secured within the vessel 1, the only movable part is the top 3 so that all danger of displacement of the parts is obviated thus rendering the apparatus as simple as possible.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

I claim:

1. In a cooker of the class described, a vessel a cellular structure mounted intermediate the top and bottom of said vessel, a metal strip carried by the bottom of the vessel and having an upstruck portion arranged below one of the cells of said structure to form a container support and spacer.

2. In a cooker of the class described, a vessel having a plurality of cells with sheet metal upstruck container supports mounted on the bottom thereof and comprising a metal strip resting flat against the bottom of the vessel and having spaced upstruck container receiving platforms.

3. In a cooker of the class described, a vessel having a plurality of communicating cells with a metal strip extending across the vessel on the bottom thereof and having an upstruck portion located in each cell to form a container support, the strip between said upstruck portion being secured to the bottom of the vessel.

4. In a cooker of the class described, a vessel having a removable closure, a cellular structure mounted intermediate the top and bottom of said vessel and fixedly secured to the side walls thereof and metal strips secured to the bottom of the vessel and each having an upstruck portion arranged below one of the cells ofsaid structure to form a container support and spacer.

5. In a cooker of the class described a vessel having a removable closure with a cellular structure secured to the side walls thereof intermediate its upper and lower ends, said structure being composed of a plurality of intersecting metal strips having interlocking slots in the lower and upper edges of the cooperating strips, and a plu-- rality of metal strips mounted on and-secured to the bottom of the vessel in spaced relation and each having a plurality of longitudinally spaced upstruck portions, one of which is arranged below each cell of the structure to provide a container support.

In testimony whereof I aflix my signature hereto.
